Reyes is the cleaner, more structured striker with higher output and better defensive metrics, and his 80% takedown defense limits Walker's opportunistic wrestling/grappling. Walker is dangerous and explosive early, but his defensive lapses, lower strike differential, and historical inconsistency against composed counter-strikers favor Reyes if his durability holds. Reyes' southpaw straight left and counters should find openings as Walker overextends, making a mid-fight KO/TKO slightly more likely than a decision in this volatile matchup.
